PRINTING-RECORDER.

SPECIFICATION forming part of Letters Patent No. 420,619, dated February4, 1890. Application filed July 13, 1888- Serial No. 279,800. (Nomodel.)

and my invention consists in the combination of such a series oftype-wheels and devices, fully set forth hereinafter, for insuring theprinting-contact with the paper of such wheels only as contain figuresto be printed, for printing cross-lines upon the paper, and foroperating the platen and feeding the paper.

In the accompanying drawings, Figure 1 is an elevation showing part of amechanical calculator and illustrating a printing-recorder combinedtherewith and embodying my improvements. Fig. 2 is a plan of the saiddevices. Fig. 3 1s a sectional elevation showing the recorder andconnected parts. Fig. at is a transverse section on the line at 4, Fig.3.

The recorder E consists of a series of independent numbered type-Wheelshaving recesses or notches between the numbered portions and eachturning upon a shaft 23, supported by the frame of the machine andactuated by a lever 103, carrying a rack 25, which gears with a pinion22 at the side of the wheel. The movements of the rack-levers arecontrolled by operating series of keys in a manner which need not behere described, as it constitutes no essential, part of this invention,and as it is fully set forth in my Letters Patent for a mechanicalaccountant, No. 388,119, dated August 21, 1888.

In many recorders for printing numbers from'movable type-wheels it iscommon to bring all the wheels to a printing position with thecipher-mark in line with the other numbers on those wheels of a higherorder than are needed to express the said number. Thus if the number ofthe wheels is six and the number to be indicated six hundred andtwenty-one, the printed matter will. be 000621,

the preceding ciphers being unsightly and confusing. To avoid thisresult I combine with the wheels adjusting appliances whereby only thewheels from which figures are to be printed will occupy a printingposition when the printing is to be cifected, the other wheels beingadjusted to bring blank spaces in alignment with the figures that are inprinting position. This maybe effected by setting all of the wheels intoprinting position by means of the wheel-actuating devices and thenturning out of printing position the wheels of a higher order than areneeded to express the number, or the parts may be so arranged as to setall the wheels out of printing position by the action of thewheel-actuating devices, and then turning into position only thosewheels from which the printing is to be effected. The latter arrangementis embodied in the construction illustrated in the drawings, in whichthe wheel-actnating levers 103 set each wheel with the number to beprinted in a position adjacent to the printing-line, but not coincidingtherewith.

The movement requisite to turn a wheel sufliciently to carry one numberor type to the place occupied by the other number or type I term a step,and the turning of the wheels back to printing position requires amovement equal to one-half of the step movement, and this half stepmovement is effected by the upward movement of abar 120, carried by anarm 121, constituting part of a frame or carrier P, which slides on ashaft 3, the said frame consisting of said arm 121, a parallel arm 122,and connecting-bar 123. The frame P slides back and forth upon the shaft3 under the action of a spring 126, Fig. 3, which carries it in onedirection, and of a cam Q, Figs. 1 and 2, which bears upon ananti-friction roller 125 and moves the frame in the opposite direction,said cam- Q being secured to a rock-shaft 1. The frame may bereciprocated in any other manner, the means above referred to beingshown, as they constitute parts of the mechanical accountant to which Ihave already referred.

The shaft 3 turns in the arm 122 without rocking the latter; but the arm121 has a swinging movement independent of the re maining portion of theframe imparted by rocking the shaft- 3, and the rocking movement beingtransferred to the arm 121 by a rib 127, Fig. 4, which extends from thearm 121 into a longitudinal slot 128 in the shaft 3. This rocking of theshaft is imparted by hand or from any moving part of the machine withwhich the recording device is connected, and results in carrying the bar120 into and out of contact with the adjacent wheels 21.

The sliding of the frame P after the adjustment of the recorder-wheelscarries the bar 120 to a position adjacent to the wheels, and the numberof wheels that are turned by the reciprocation of the bar depends uponthe extent to which the bar is carried inward in the direction of thearrow Z), Fig. 2. If, for instance, the frame is moved until the bar 120occupies a position opposite four of the wheels, the reciprocation ofthe bar will then move these four wheels one -half a step, bringingtheir type into printing position, the remaining wheels being out ofprinting position. If the frame P is moved until the bar is oppositeonly one wheel, that alone will be turned a half a step, or the frame Pmay be arrested immediately after its movement begins,in which case allthe wheels will be set in printing position by the movement of the bar.

It will be evident that different forms of carriers in the shape offrames or otherwise may be employed for carrying and reciprocating thebar.

It is desirable to automatically set the bar in lateral position,according to the number of wheels that are set or operated to record thedesired number, and one means of effecting this in the construction ofapparatus illustrated is by means of a series of pawls g and levers F,arms 1) of which GKLQDd over the pawls and between springs c and lugs106, carried by the levers 103, so as to carry said levers 103 withthem. Normally the long or heavy end of each pawl g is elevated so as tobe out of the path of a lug or projectioni upon the frame P, Figs. 3 and'.l, and the said frame is normally in a position with the bar 120opposite all of the printing-wheels, and its end is in line with saidlug.

Upon operating the devices that actuate the wheels, the forward ends ofthe levers F drop and the rear ends of the arms 1) rise as they begin tomove the rack-levers 103, and the initial movement of each arm 1)results in permitting the heavy end of the adjacent pawl to dropdownward. After the desired number has been set up upon the recorder,the shaft Z is rocked to permit the frame P to slide under the action ofthe spring 126,when it will move to the right, Fig. 4, until it strikesthe first of the pawls g that is in its path. As only the pawls aredropped that are connected with such. type-wheels as are operated to setup the numbers to be printed, and as such pawls determine the positionof the frame P and bar 120, the latter will occupy a position adjacentto only the printingwheels that have been moved to record a number. I donot here claim a platen carried by a frame movable by a spring towardthe type-wheels and thrown from the latter and released by reciprocatingdevices, as this is the subject of a claim in my application for apatent, Serial No. 278,907, filed July 3, 1888. After the parts havethus been set in position the shaft 3 is rocked by hand or otherwise,thereby bringing the bar 120 against the opposite type-wheels and movingthem each one-half a step to bring their type into printing position.After the printing is effected the levers F are moved so that arms I)are brought in contact with the pawls g and lift the latter, while thelevers 103 are all carried downward to restore the recorder to zero,after which the frame P may be moved to its first position.

To the arm 122 of the frame P is pivoted a finger 12%, the inner end ofwhich is adjacent to that of the bar 120, but on a different horizontalplane, so that the said finger is carried longitudinally by the fame Pthrough the notches of such of the wheels as are not to make a record,and said finger 124: is thrown normally inwardly by a spring 131. Thesaid finger has a rib a at its outer edge, and has a beveled end on,which, when it contacts with a beveled shoulder s on any part of theframe, (as, for instance, one of two side plates 21,) will cause thefinger to be thrown outward and bring the rib a into position to print across-line upon the paper, which receives the impression from the typesjust below the last number printed by said types.

The movable line-bar or finger maybe supported by any movable carrieradapted to carry it back and forth in front of the wheels.

The ink-ribbon Q is carried by two spools on shafts 8 0 and acrossguide-rollers q g between the recorder and the platen, which, as shownin Fig. 1, is in the form of a roller S, and the strip of paper V passesbetween the platen and the ribbon. In the construction shown the rollerS is carried by a swinging frame R, which supports at the upper end aknife 05, against which the strip of paper may be drawn to tear offsections as required. The frame R is pivoted upon or carried by a shaft405 in bearings in the frame of the machine. A spring a bears againstthe frame and tends to throw it inward, and the outward movement of theframe is effected from the rocking of the shaft 3 through the medium ofa pawl a, hung to an arm 135, carried by the shaft 3, and socketed atthe end to receive a roller a, carried by the frame R. The arm 135 isprovided with a pin 0, in position to strike the heel of the pawl a whenthe arm 135 moves in the direction of the arrow, Fig. 1, so that afterthe frame R has been thrown outward to a certain extent the outer end ofthe pawl a; is raised from the roller or, when the frame R will swinginward suddenly,

bringing the platen forcibly against the paper and the latter forciblyagainst the ribbon lying upon the type.

The strip ofpaper may be fed by carrying it between the roller S and anunder roller S, and by imparting a feeding movement to one of therollers. Thus an arm 3 swings upon the shaft 3 of the roller S andcarries apawl s thrown by a spring 5 against the edge of the roller S,so as to bite thereon, when the arm 5 swings in the direction of thearrow, Fig. 1.

The swinging movement of the arm is effected after each printing actionby any suitable actuating devices. For instance, a stationary slottedarm T is arranged in position for its slot 8 to receive a stud 8extending from the arm 3. When the frame R moves outward, the arm .9will swing in the direction of its arrow, and the pawl s will bear onand turn the roller S and feed the paper. When the frame R swingsinward, the arm 8 will swing outward, and the pawl s will slide over theperiphery of the roller S without moving the latter. 1

The movement of the ribbon is effected by each movement of the arm 135,to which is connected a link 211, connected with an arm 1?, thatvibrates upon the shaft 8, and which carries a pawl 15, that engageswith the teeth of a disk 212, carried by the shaft 8.

\Vithoutlimitiug myself to the precise construction and arrangementofparts shown, I claim- 1. The combination, with the printingwheels of arecorder, each having a series of peripheral type and interveningnotches, of a reciprocating bar and a vertically and longitudinallymoving carrier therefor, whereby said bar may be brought oppositely toone or more of the wheels and vibrated to turn said wheels,substantially as set forth.

2. The combination, with a series-of independent recording-wheels andactuating devices by which the wheels are turned to set their type outof printing position, of a bar sup cupy a printing position,substantially as set forth.

4. The combination, with the independently-movable printing-wheels of arecorder and wheel-actuating devices, of appliances for turning thewheels to bring into printing-line only those which are to print,substantially as set forth.

5. The combination, with the printingwheels, actuating devices, bar 120,and frame carrying said bar and provided with a lug t, of a series ofpawls arranged to contact with the wheel-actuating devices and to moveinto and out of the path of the lug, substantially as set forth.

6. The combination, with the series of printing-wheels of a recorder, ofa line-printing finger 124, substantially as set forth.

7. The combination, with the printingwheels of a recorder, of acarrier,a1ine-finger supported thereby, and devices for moving thecarrier and the line-finger, substantially as set forth.

8. The combinatiomwith the swinging frame R, rollers S S, and arm .9carrying a pawl .9 of a stationary arm T, having a slot, and a stud uponthe arm .9 extending into said slot,

substantially as set forth.
